Description
Description
This system is recommended for use on a 4-Link Rear Air Suspension System. It can also be used for a 4-Link Front only suspension or is commonly used with the 2-Stage Front and 4-Link Rear Air Suspension kits on stock height/leveled trucks. This system is designed to control your air suspension with nearly hands-free operation. On a 4-Link Rear Air Suspension, the system will automatically inflate/deflate, as needed, to maintain the proper ride height of the suspension. This is determined by the location of the height control valves on each side of the suspension. The only control you/the driver will have over the suspension is with the dump valve switch. Activate the dump valve switch with the provided in-cab control panel, and the suspension will lower down 4″ or so until it reaches the airbag’s internal bump stops. Press the dump switch again and it will automatically return to ride height. When using a 2-Stage Front Air Suspension System, add an extra pair of Mechanical, Height Control Valve Linkage Kits (HCVLKs) for the system to automatically adjust at all four corners
Kit includes: 100% duty cycle VIAIR compressor, 3-gallon air tank, (2) height control valves, (2) dump valves, pressure switch, relay, control panel wiring, fittings, air line, etc.
*Air dryer optional
